Copeland 998-0746-00 Valve 321702-401 The piloted diaphragm design allows

The piloted diaphragm design allows for a broad operating pressure differential

This narrow threshold helps prevent catastrophic mechanical failure by cutting the 24V circuit to the contactor before oil slugging or overheating occurs

This kit is engineered specifically for Copeland Comfort Control (Alco) 200RB and 200RD series valves from port sizes 2 through 6

Copeland 998-0746-00 Valve 321702-401 The piloted diaphragm design allowsThe Copeland 998 0746 00 Discharge Temperature Control (DTC) Valve is a critical liquid injection component designed specifically for low temperature scroll compressors. As a veteran technician knows, scroll sets in low temp applications lack the thermal mass to dissipate heat effectively. This DTC valve acts as the compressor's internal cooling system, utilizing a thermostatic element with a 194F sensing bulb. When dome temperatures hit this
